I gather you are in AF-F mode since it's video right? It's either AF-S or AF-F I think, AF-C being for still images....anyway, this is how the manual describes AF-F:Full time-servo AF: For moving subjects. Camerafocuses continuously until shutter-release buttonis pressed. Focus locks when shutter-releasebutton is pressed halfway.Isn't what you describe just what should be happening? ...i.e. the camera is focusing and refocusing until the shutter is pressed 1/2 way to lock it.You don't mention pressing the shutter half way or at all so I gather you are not right?
